Geologic Mapping of the Av-4 Domitia Quadrangle of Asteroid 4 Vesta

Introduction: NASA’s Dawn spacecraft entered orbit of the inner main belt asteroid 4 Vesta on July 16th, 2011, and its one year survey allows characterization of the geology, elemental and mineralogical composition, topography, shape, and internal structure of Vesta before departing to asteroid 1 Ceres in late 2012. As part of the Dawn data analysis the Science Team is conducting geological mapping of the surface, in the form of 15 quadrangle maps. This abstract reports results from the mapping of quadrangle Av-4, named Domitia after the Roman vestal virgin.
